Description: Cytron MD20A
Single-channel DC motor controller based on MOSFET transistors. Enables control of motor speed through PWM channel. Continuous current per channel is 20 A (momentary 60 A). Supply voltage from 6 V to 30 V. For proper operation the module does not require an additional Arduino type controller, the controller can be controlled by means of buttons on the board.
Cytron MD20A can be controlled via PWM and DIR inputs. Logic voltage ranges from 1.8 V to 12 V and is compatible with most controllers such as Arduino, RaspberryPi, PLC.
The module also has overcurrent protection to protect the controller from damage when the motor stops or when a motor is too big. In case the motor tries to draw more current, the controller limits it to the maximum. The controller also has protection against too high a temperature. If the board temperature increases, the current limit is limited.

Attention! The controller does not have protection against reverse polarity, pay special attention to the way of connecting the module power supply. |
